- Your Exchange admin can run the following command in Exchange Management Shell:
Get-ExchangeCertificate | Where-Object {$_.Services -match “IIS”} | FL
The command will enable you to view the certificate assigned to your IIS service.
Now check if the OAB URL you got in the last step matches the CertificateDomains of the certificate. In case the OAB URL is missing, then ask the Exchange admin to update it.Using an OST recovery software | Ultimate solution
